The award-winning EnviroSCAN probe is the flagship product of Sentek. It provides the user with great flexibility for precision monitoring of moisture and salinity at multiple depths in a soil profile.

The EnviroSCAN probe first made its mark in irrigated agriculture, resulting in water savings of 30-50% and substantial yield and quality benefits. Today it is widely used in all forms of irrigated and dryland agriculture, environmental applications, research and education, as well as turf, parks and gardens.

The EnviroSCAN probe is the only commercially available product that allows for monitoring to great depths (up to 40 metres) using the same profiling probe.

Minimum soil disturbance during installation, leading to measurement of an undisturbed soil profile

Single Point Sensor

The single point sensor is 10.5cm (4”) in size and can measure soil moisture + temperature or soil moisture + temperature + salinity.
The sensor can be completely buried in the soil. Unlike other single point sensors, the sensor measures volumetric water content for the length of the sensor. Sentek has developed,
and continues to develop, a number of soil specific calibrations that can be applied to the data to help you make sense of the readings. Two cabling options are available, one where
the cable exits from the side of the unit, and the other where the cable exits out the top of the unit.

The Drill & Drop is a fully encapsulated, easy to install, soil measurement probe. Probes are available in four lengths, 30cm (12") (SDI-12 only), 60cm (24”), 90cm (36") and 120cm (48”), with sensors fixed at every 10cm (4”) increment. It is also available as a single point sensor. Purchase options are any length with soil moisture + temperature sensors or soil moisture + temperature + salinity.

Due to the ease of install and protected electronics, the Drill & Drop is ideally suited to situations where a monitoring probe may need to be moved between sites in short-term and annual crops. Having the electronics completely encapsulated and able to be completely buried also makes the probe suited to long-term installations, where machinery will pass often, such as dryland and feed crops. Being able to leave the probe in the ground means long-term, uninterrupted data trends and comparison between seasons is possible.

The Drill & Drop also covers the issue of data continuity and integrity where the probe does need to be reinstalled. The ingenious tapered probe and matching auger allows direct, slurry-free, installation. This direct installation method means that the probe is measuring ‘real’ representative soil conditions immediately after install, because the surrounding soil has not been disturbed.
